Our Services

Once a system is designed and the client is happy to proceed, Air Improve Limited can begin the process of installing the equipment. We install all types of air conditioning and ventilation systems throughout the whole of the UK. Each system is very different to the next one depending on the environment it is due to be used in, frequency of use and also what the general requirements for the system are.
The Sales Engineer who you deal with will make sure you get the right system for your requirements every time and is qualified to answer any questions you may have. Accredited by Safe Contractor, Construction Line and Refcom Elite. We are also Daikin D1+ premium partner. Air Improve is fully qualified to give you the best advice possible.

Maintenance is a vital tool in prolonging the life and efficiency of your air conditioning equipment. We find using the analogy of purchasing a car is the best way to show the benefits of maintenance. If you did, it wouldn’t be long before the car started experiencing problems. Air conditioning is no different. In fact, to make sure the warranty (which is up to 7 years with some manufacturers) is not void, you must have the equipment serviced as per the manufacturers guide lines at least once a year.
Regular maintenance is not just to comply with the manufacturer’s warranty. The United Kingdom has recently revised the refrigerant leak checking criteria for all refrigerants regardless of volume, based on potential CO2 equivalent emissions following the accidental release of refrigerant to atmosphere and the Global Warming Potential (GWP). The onus is on the operator and Service Provider to keep and maintain records for up to five years to ensure that the systems are being checked.

We like to think that if you have your equipment regularly serviced, the system stands an increased chance of performing to its highest efficiency without any problems. However, we are dealing with technology and we all know technology sometimes doesn’t want to work the way we would like it to. Air Improve Limited has a dedicated breakdown team who are on hand to make sure that if your air conditioning equipment is playing up, it will be repaired and back performing how it should in no time.
Many other air conditioning companies incorporate their breakdown cover in the cost of their maintenance contract. However, Air Improve do not believe we should be charging for something the client may not actually need or benefit from, so we keep our proactive (maintenance) and reactive (breakdowns or repairs) cover separate.
